Abstract

A micro-vaporizer has an annular main body, a vaporization chamber, and a liquid delivery arrangement. The liquid delivery arrangement is configured for sequential delivery of a plurality of vaporizable liquids to the vaporization chamber. The liquid delivery arrangement has an annular wick having an internal wick surface defining at least a portion of the vaporization chamber. The liquid delivery arrangement also comprises a liquid reservoir surrounding the wick. The liquid reservoir is configured for storage of at least one vaporizable liquid therein and is in fluid communication with the wick. A heating element is positioned within the vaporization chamber for heating and vaporizing vaporizable liquid at or near the internal wick surface.

Claim(s)

1 . A micro-vaporizer comprising: an annular main body defining a main body interior; a vaporization chamber within the main body interior; a liquid delivery arrangement configured for sequential delivery of a plurality of vaporizable liquids to the vaporization chamber, the liquid delivery arrangement comprising an annular wick having an internal wick surface defining at least a portion of the vaporization chamber, a wick casing having a circumferential casing wall surrounding the annular wick, the casing wall having a liquid flow opening formed therethrough, and a liquid reservoir surrounding the wick casing and configured for storage of at least one vaporizable liquid therein, the liquid reservoir being in fluid communication with the wick via the liquid flow opening in the casing wall; a heating element disposed within the vaporization chamber, the heating element having a heating surface adjacent or in contact with at least a portion of the internal wick surface for heating and vaporizing vaporizable liquid at or near the internal wick surface; an air flow passage from one or more air intake openings in the case wall to the vaporization chamber, the air flow passage providing a path for air from an external ambient environment to flow into the vaporization chamber for mixing with vaporized liquid to form a vaporization mixture; and a vaporization mixture flow passage extending from the vaporization chamber to an exit port.
